RFC 7142RFC 1142 to Historic February 20141. Introduction
IS-IS is the "OSI Intermediate system to Intermediate system intra-
domain routeing information exchange protocol for use in conjunction
with the protocol for providing the connectionless-mode Network
Service (ISO 8473)", otherwise known as ISO/IEC 10589. It has been
extended for use with IP by RFC 1195 [RFC1195] and subsequently
enhanced by many other RFCs.
RFC 1142 [RFC1142] was a republication of ISO DP 10589 originally
provided as a service to the Internet community. However, ISO DP
10589 was an ISO "Draft Proposal", which differed in a considerable
number of significant respects from the final standardized version
published as ISO/IEC 10589 [ISO10589-First-Edition], and subsequently
revised as ISO/IEC 10589 Second Edition [ISO10589-Second-Edition].
It has been an ongoing source of confusion when RFC 1142 has been
unwittingly quoted or referenced in place of ISO/IEC 10589 itself.
All references to IS-IS should be to the latest edition of the IS-IS
standard (currently ISO/IEC 10589:2002, Second Edition), and RFC 1142
is only of historic interest.
This memo explains why RFC 1142, "OSI IS-IS Intra-domain Routing
Protocol", is reclassified to Historic status. This memo also
obsoletes RFC 1142.
2. Security Considerations
Reclassifying RFC 1142 has no security considerations.
